Why would God send an archangel that He could create or destroy with a thought to die for the sin of mankind? It would not be a sacrifice for Him at all. No, He sent His Son, a real sacrifice for Him, not a created being. And I have to note that we have reached your final defense, the venerable, "You guys translated it wrong, we did it right". The only problem with that is, our Bible was translated from the original languages by people who could read those languages. Yours, not so much.
Tell us, in what way was the KJV altered, and how do you know this since you don't read Hebrew and Greek?
